Are you not aware of Dirk or Durant? Bigs that can shoot are nothing unusual in the NBA, ever since Bob Pettit (probably even before him) there's always been some assortment of 6-9+ guys that can stretch the floor with a highly polished jumper. He's not quite 6-9, but Kevin Love is another 'big' that stretches the floor well with a long range jumper.

When I think bigs, I think guys who play the PF or C spots. So u gotta roll with Dirk, who's the best shooting big man of all time. U gotta be able to stick it from practically anywhere not just midrange. Dirk and Love are the top two in my book as of now.
